Applications
Bottle-top dispensers like the Zippette are standard tools in chemistry, biochemistry, microbiology, and general analytical laboratories. They are used for delivering fixed or adjustable volumes of acids, bases, solvents, buffers, and other reagents directly from the reagent bottle, eliminating repeated pipetting and reducing operator fatigue and the risk of spills or contamination. The Sigma Techware Zippette line was designed to bridge benchtop convenience with the accuracy demands of quantitative lab work, offering a compact form factor suitable for routine dispensing tasks such as media preparation, sample dilution, titration setup, and buffer addition. The included multiple bottle adapters allow a single dispenser to fit a range of standard laboratory bottle neck sizes, making it versatile across common reagent packaging. These dispensers remain in active use in research, quality control, and teaching laboratories worldwide.
This Sigma Techware Zippette D-6544 Bottle-Top Dispenser appears to be in good used condition. It comes in its original blue retail box with the foam tray insert intact, and includes the dispenser body, three white bottle adapters, the discharge tube, a small cleaning/assembly tool, and the original Certificate of Quality Control and Instrument Warranty. The dispenser body shows no significant wear — the black finish and red accent rings are clean, and the volume scale markings are clear and legible. The box itself shows some shelf wear on the exterior corners, consistent with storage. This unit was pulled from a working laboratory environment.
